SRUCTURE OF ORTHENTHOSE

A new tetrasaccharide, orthenthose, has been isolated from the dried twigs of Orthenthera viminea (Family: Asclepiadaceae).By spectral and chemical procedures, this new tetrasaccharide has been shown to be O-α-L-oleandropyranosyl-(1-->4)-O-α-L-oleandropyr

Preparation of Some Acetylated Deoxy-pento- and -hexofuranoses and their Deacetylation

Acetylated 2-deoxy-, 3-deoxy-, 2,3-dideoxy- and 2,3,6-trideoxy-furanoses have been prepared by reduction of the corresponding acetylated deoxyaldonolactones with disiamylborane. An improved procedure for the isolation of the reduced products is described.

A PREGNANE ESTER AND ITS GLYCOSIDE FROM ORTHENTHERA VIMINEA

A new pregnane ester named ornogenin and its diglycoside designated as ornine were isolated from the dried twigs of Orthenthera viminea.On the basis of chemical and spectroscopic evidence, their structures were established as 12,20-di-O-cinnamoyl-sarcosti

A PREGNANE ESTER DIGLYCOSIDE FROM PERIPLOCA CALOPHYLLA

A new pregnane ester diglycoside of ornogenin named as plocinine was isolated from the dried twigs of Periploca calophylla.On the basis of chemical and spectroscopic evidences its structure was established as 12,20-di-O-cinnamoyl sarcostin-3-O-α-L-oleandr
